Does anyone know why Zetor changed from the 3.9 L engines that were in the Super tractors to the 4.2 L engines that are currently in the Proxima tractors? I am somewhat unfamiliar with Zetor tractors, but I read somewhere that the 3.9 L engines had individual cylinder heads, while the 4.2 L engines have a traditional one piece head. Is this true?
